Has your vacuum cleaner lost the suction? Are you now considering buying another one? While you are here, you don’t have to because we have a solution for you. We are going to show you how you can fix a vacuum cleaner with no suction.

Fortunately, it is not that difficult to repair a vacuum that has lost suction as it sounds. And there are usually 5 main reasons why that can be causing the headache. These are either a blocked filter, hose, full bag, airflow gaps, or a defect in the motor.

We are going to see how you can fix each of these problems.

Step By Step Guideline

Blocked / dirty filter

Most vacuum cleaners have a filter, the pre-motor filter. This is to prevent particles from getting into your vacuum cleaner and damaging the motor. Due to the activity of the filters, they can immediately become dirty clog – and in such a case. The suction of your device is impeded.

The removal of a dirty/clogged filter on your device is generally done directly. Once you’ve determined where the pre-engine filter is essential:

1. Take it from the vacuum cleaner

2. Shake off

3. Wash the filter in warm water

Blocked hose

At the point where you look at the dirt and trash your vacuum cleaner comes into contact with. It shouldn’t be a real astonishment that blockages can and do happen. The best-known area of your vacuum cleaner where the negative effects of blockage occur is the hose. This reduces the sucking speed, but it is also easily removed.

Basically, disconnect the hose and give it a quick overview of any blockages. If blockages are found, most of them can be loosened with a floor brush handle or a plastic jacket holder. Although care has been taken not to use too much force as you would rather not cut the hose. It is also mandatory while the hose is detached. Give the area where the hose is connected with your vacuum a quick check to make sure there are no blockages.

Blockages in your model are not limited to the hose. But can also occur around the brush roller, with hair and various strands being the main cause of such blockages. Fortunately, the blockage around the brush roller can be cleared several times out of ten by cutting off the filaments/hair that tangle around the part without having to separate the brush roller.

Full bag/cylinder

From the beginning, the limit of your bag/cylinder seems to be very high. But it should not be forgotten, the fuller the bag/cylinder gets, the less suction power your vacuum cleaner offers – all in all. It is important that you ensure that you empty normally the vacuum.

As a general guideline, it is recommended that both be invalidated before they are 66% full.

Regardless of emptying the vacuum cleaner bag, it is also important that you consistently replace it with another one. This is because the pores in the collector can be blocked by debris, which in return reduces the air penetrability.

Airflow gaps

If, when using the hose connection, you find that your model is extracting significantly, there is a possibility that you have a hole in the airflow. In fact, even the smallest gap can reduce the advertised suction power.

Amazingly, after some time, the hose of your vacuum can experience the negative effects of mileage that make such gaps almost certain – pulling the hose when using the vacuum is a typical purpose when parts and openings occur. If you are damaged in any case, you need to get a replacement vacuum hose and attach it to your vacuum instead.

A defective Motor 

If after checking the four areas the suction power of your vacuum cleaner is still not sufficient. There may be a problem with the motor or the carbon brushes. In this case, you should change the motor or the carbon brushes.

Changing the carbon brushes or the motor on your vacuum cleaner can be a very tedious and dubious affair. This is the reason why this is only recommended if it is an extremely simple device.

If you take the opportunity to routinely clean your vacuum cleaner bag/cylinder, clean the filters and remove blockages. You can let your vacuum cleaner work at peak performance over a longer period of time.


With these five main issues, if you troubleshoot and see it is none of the problems, expect your vacuum to regain its suction power. However, if it is not working to your expectations, consider seeking the help of an expert repair.
